Specification of Letters Patent.

Patented April 20, 1909.

Application filed December 24, 1908. Serial No. 469,099.

Be it known that I, ROBERT E. WILK N- SON, a citizen of the Unlted States, residing at Kenosha, in the county of Kenosha and State of Wisconsin, have invented certain new and useful Im rovements in Antirattlers for Windows, 0.,- of which the followin is aspecification'.

- 's invention relates to improvements in anti-rattlers for windows, etc., and it has for its salient objects to provide an extremely simple, and therefore economically constructed, device which is capable of unusually wide range of adjustment to suit differin' conditions; to provide a device which may e very conveniently applied and de- 7 tached and may therefore be conveniently .carried by traveling men; to provide a des applie in such manner that the opening or closing of the window is not prevented nor can the device be injured by such operation and in general to provide an improved device of the character referred to.

Figure 1 is a fragmentaryperspeotive view of a window equipped with two of my devices'and showing particularly the different manners of insertlng the same between the sash and casin members. Fig. 2 is an edge view of one of my anti-rattlers part of the chain being broken away. Fig. 3 is an end vi ce whic elevation of the same taken at right angles to the-view shown in Fig. 2. In its most approved form, viz. that shown 1n the accompanylng drawmg, I construct the device proper a of a stamping or blank of sprin sheet metal,prefera )ly of bronze or hard rass.

The device is preferably of elongated ellip tical form as best shown in Fig. 3, and after so proportion being blanked out is shaped in a suitable former to give it an ap roximately bow shape throughout its chle length, as indicated at b, terminating at one end in a reversed curved portion 0 and at its opposite end in a straight or fiatetipped portion (1. I prefer to use metal of about 27 gage and 1 the curve or how of the device that when in its normal or unsprung shape .it will be curved sufficiently to occupy as wide a crack as is likely to be found between the window sash stile and the stop of any ordinary window. The resiliency of the metal is such, and the curves into which the device is formed such that it may beflattened out almost perfectly fiat without straining the metal beyond its elastic limit, '5. c. without permanently changing its form. According] the device may be used to prevent rattling etween arts in any crack from one of substantially t e same width as the thickness of the metal to one which is as wide as the distance between the convex side of the device in its normal shape and a plane touchingthe opposite side of the curve 0 and the corresponding side of the tip d.

For convenience of mounting the device so that it will alwa s be retained in proper associationwith the sash stile, I attach the chain c and screw-eyefto the ourved'end c of the device.

In use the anti-rattler is ap lied between the sash stile and the sto or etween other parts which are to be he (1 under tension in various positions depending upon the width of the crack. If the crack is quite small the tip end (i will be inserted into the crack, the longitudinal axis of the device being arranged about at right angles to the stile, as seen clearly in the up er part of Fig. 1. If the crack is so wide t at the tip (1 and the body portion of the device immediately adj acent to the tip are not sufficient to occupy the space and hold the sash under tension,

a screw-eye and inserting it in a direction a proximately arallel with the plane of tlie sash and insi e of the face plane of the latter so that should the sash be moved past the meeting rail of the other the screw-eye does and injured between the sash.

I preferably nickel plate or otherwise finish the sheet metal so that it retains its permanent finished appearance.

It will be obvious that the device is one that it is formed in the ranges of its capacity;

that it readily of a single piece of such shape suggests to the user not interfere nor is the anti-rattler caught how it had best be apthen the device is turned sidewise and insertvice to the sash is best accomplished by using whichimay be made at a minimum cost in large qu antlties; that it is self-adjusting withv plied to secure the best results and that'it is i efiective anddurable. I It be understood thct'the. device ma.

be somewhat modified without departing 5 from the spirit of the invention.

- I claim asmy invention 1; An anti-rattler for Windows consisting of an elongated resilient sheet-metal plate adapted to be removably inserted between 10 the meeting sides of the sash and casing and having rounded ends and permanently bowed between its ends, said bowed portion merging smoothly at oneend into a reverselycurved portion and at its opposite end into a fiat tiapl'portion lying approximately the gener plane of the device as a. whole.

2. An anti-rattlerfor windows adapted to be removably inserted between the meeting sides of the sash and easing of the window, and comprising a plate formed of spring sheet metal, ofelongated form, rounded at its ends, bowed between said ends, and provided with a chain and screw eye attachment.
